Fresh hacks every day
[Paul Stoffregen], the brains behind the popular and very capable Arduino-compatible Teensy development board, has offered his contribution to the explosion of ARM-powered boards with the Teensy 3.0.
The original Teensy is an AVR-based development board that goes far beyond the official Arduino offerings. The new and improved Teensy 3.0 improves upon an already wonderful platform with a 32 … Read the rest
[Angus McInnes] has been working on AM radio transmission techniques. He tried out a method of using a VGA port for the task but found the vertical blanking was audible. His latest experiments use a Teensy microcontroller board as an AM transmitter.
This is not a standalone solution, but rather a hardware extension for his laptop. This is because … Read the rest
As [Brad] over at the LVL1 hackerspace watched his friend build a Laser tag/tazer mashup for Makerfaire Detroit 2012, he noticed these new laser tag guns were really cool. These Light Strike guns have an impressive array of electronics for a $30 toy, but there was still much to be desired. [Brad] decided to reverse engineer these guns and work … Read the rest
We have to agree with NYCResistor, the exclusion of numeric pads from laptops is a real loss for productivity. Ever try to working with a huge spreadsheet ledger without a 10-key? Sure, there are usually function key alternatives hiding somewhere on those reduced keyboards. But that’s hardly the same thing. We think it’s time to take back the numpad. This … Read the rest
This is the bee counter which [Hydronics] designed. It’s made to attach to the opening for a hive, and will count the number of bees entering and exiting. We’re not experienced bee keepers ourselves (in fact we’re more of the mind of getting rid of stinging beasties) but we understand their important role in agriculture and ecosystem so we’re … Read the rest
[Kevin Osborn] is making it a bit easier for young programmers to write programs that interact with the physical world. The device he’s holding in the picture is an Arduino based accelerometer and distance sensor meant for the Scratch language.
Scratch is a programming language developed at MIT. It has kids in mind, and focuses on graphical building blocks. … Read the rest
This is the senior design project for a group at the University of Vermont. It’s a wet, bubbly, blinky, interactive thing. Each column is a clear tube filled with water, with a string of fully addressable RGB LEDs suspended in the center. In idle mode, the lights scroll through a series of interesting patterns while the water is filled … Read the rest
